How
to
Use
this
Manual
Many people read their owner’s manual from beginning
to
end when they first receive their new vehicle.
If
you
do
this,
it
will
help
you
learn about
the
features and
controls for your vehicle. In this manual, you’ll find
that pictures and words work together to explain
things quickly.
Index
A
good place to
look
for what
you
need is the Index
in
the
back of the manual. It’s an alphabetical
list
of
all that’s
in
the
manual, and the page number where
you’ll find
it.
Safety Warnings and
Symbols
You will find
a
number
of
safety cautions
in
this
book.
We use
a
box and
the
word
CAUTION
to tell you
about things that could hurt you
if
you
were to ignore
the warning.
A
CAUTION:
These mean there is something that
could
hurt
you
or other people.
In
the
caution area, we tell you what the hazard is. Then
we tell
you
what to do
to
help avoid or reduce the
hazard. Please read these cautions. If
you
don’t, you or
others could be hurt.
iii
You will also find a circle
with
a slash through
it
in
this book. This safety
symbol means “Don’t,”
“Don’t do this,”
or
“Don’t
let
this happen.?’
In
the notice area,
we
tell you about something
that
can
damage
your
vehicle.
Many
times, this damage would
not
be covered by your warranty? and it could be costly.
But
the
notice
will
tell you what to do to help avoid
the damage.
When you read other manuals,
you
might see
CAUTION and NOTICE warnings
in
different colors or
in
different words.
You’ll also see warning labeis
on
your vehicle.
They
use
the
same words,
CAUTION
or
NOTICE.
Vehicle Damage Warnings
Also,
in this book you will find these notices:

NOTICE:

These mean there
is
something
that
could
damage your vehicle.

Here you’ll find information about the seats
in
your
vehicle and how to use your safety belts properly.
You
can also learn about some things
you
should
not
do with
air bags and safety belts.
Seats

Mar--a1 Front Seat
CAUTION:
You
can lose control of the vehicle
if

you
push a pedal when
you
don’t want
to.
Adjust the driver’s seat only when
the vehicle
is
not moving.
If
your vehicle has a manual
bucket, split bench
or
full
bench seat,
you
can adjust
it
with this lever at the front
of the seat.
~
I
Slide the lever at the
front
of the seat toward the
passenger’s side to unlock
it.
Using your body, slide the
seat
to
where
you
want
it.
Then, release the lever and try
to move the seat with your body
in
order to make sure
the seat
is
locked
in
place.
1-1
Power
Driver’s
Seat
(Option)
If your vehicle has a power seat on the driver’s side,
you
can
adjust
it
with these controls at
the
outside edge
of
the seat.
You can use the round center knob
to
move the seat
where
you
want it.
To
raise the seat, move the knob up.
To
lower the seat, move the knob down.
To
move the
seat forward, move
the
knob toward
the
front of the
vehicle.
To
move the seat rearward, move the knob
toward the rear of the vehicle.
You can also raise and lower the front and rear

an upright position.
1-3
But
don’t have a seatback reclined
if
your
vehicle
is moving.
A
CAUTION:
Sitting in
a
reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can’t do their job when
you’re reclined like this.
The shoulder belt can’t do its job because it
won’t be against your body. Instead, it will be
in front of you. In
a
crash you could go into it,
receiving neck or other injuries.
The lap belt can’t do its job either. In
a
crash the
belt could
go
up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle
is
in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety
belt properly.
1-4
Head traints
Slide the head restraint up
or
down
so
that the top
of
the
restraint is closest
to
the top of your ears. This position
reduces the chance
of
a
neck injury
in
a
crash.
Seatback Latches
The
front
seatback
of
the
base level bench seat folds
forward to let
you
access the rear
of
the cab. Your
seatback will move back and forth freely, unless
you
come
to
a sudden stop. Then
it
will lock
in
place. If
you
have a Crew Cab, your front seatback is designed
not
to
fold forward. Access
to
the
rear of the cab is available
by using the rear doors.
The front seatback of all seats except
the
base level
bench seat folds forward
to
let
you
access
the
rear
of
the
cab.
If
you have
a
Crew Cab,
your
front seatback is
designed
not
to
fold forward. Access

I
If
any easy entry seat isn’t locked, it can move. In
a sudden stop or crash, the person sitting there
could be injured. And, even if there is no crash
or
sudden stop, a driver sitting in an unlocked easy

Safety Belts: They’re for Everyone
This part
of
the
manual tells
you
how
to
use
safety belts
properly.
It
also tells you some things you should
not
do
with safety belts.
And
it
explains the Supplemental Inflatable Restraint
(SIR),
or air bag system.
Don’t

a
safety belt properly.
If
you
are
in
a
crash and
you’re not wearing
a
safety
belt, your injuries
can be much worse.
You
can hit things inside the
vehicle or be ejected from it. You can be seriously
injured or killed. In the same crash, you might
not be if you are buckled up. Always fasten your
safety belt, and check that your passengers’ belts
are fastened properly too.

Your vehicle has a light
that comes on as a reminder
to buckle up. (See “Safety
Belt Reminder Light” in
the
Index.)
In most states and Canadian provinces, the law says
to
wear safety belts. Here’s why:
They
work.
You never know if you’ll be in a crash. If you do have a
crash, you don’t know
if
it will be a bad one.
A few crashes are mild, and some crashes can be
so
serious that even buckled up a person wouldn’t
survive.
But
most crashes are in between.
In
many
of
them, people who buckle up can survive and sometimes
walk away. Without belts they could have been badly
hurt
or killed.
After more than
25
years of safety belts in vehicles,
the facts are clear. .In most crashes buckling up does
matter
...
a lot!
Why Safety Belts Work
When you ride in or
on
anything, you
go
as fast
as
it goes.
Take the simplest vehicle.
Suppose
it’s just a seat
on
wheels.

up

doesn’t stop.

A:
Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only;
so
they work

safety belts

not instead
of
them. Every air bag
system ever offered for sale has required the use
of
safety belts. Even if you're in a vehicle that has air
bags, you still have
to
buckle up to get the most
protection. That's true not only in frontal collisions,
but especially in side and other collisions.
